I am planning on redoing the exterior of a house I just bought. It seems like the exterior is made of some sort of stamped stucco to make it look like bricks (I am going to attach pictures). Some of this "brick" is falling apart and just looks terrible. Does anyone have any experience with this? Do I need to remove them and then apply stucco or canI just lay stucco on top of the current material. The problem is I am not sure what type of material this is. The chunks that are coming off are about 3/4 inch thick. Underneath the material is concrete. On the picture of a door you can see that an extension was made to the house and has a straight stucco look, which is what I am hoping to have all over. How do I go about replacing the exterior? Any advice is appreciated.
